Water is necessary for carrying nutrients to your cells, flushing bacteria from your system, preventing dehydration, and replacing fluids lost from sweating, but you may not need to drink as much as you thought.
Stephen R. Daniels. pediatrician. No. You shouldn't give your newborn water or sugar water. And if you're feeding powdered or concentrated formula to your baby, never dilute it with more than the amount of water called for on the label. Your infant will get all the necessary hydration from breast milk or formula.
When your child is old enough for solids, small sips of water are okay. As a newborn, however, water should never be offered because many times it would take the place of a feeding. Also, too much water can prove toxifying. Wait until your baby has solids, and even then don't offer too much until at least 8 to 10 months. posted 09/04/2007 by Vaughn Kauffen.
